Specification of Letters Patent No. 10,588, dated February' 28,1854. I

VTo all whom t may concern.:

Be it lmown that I, STEPHEN of Boston, in the county of Suffolk andState of Massachusetts, have invented certain new and usefulImprovements in Printing- Presses, which I denominate a Combinaftion-Press; and I do hereby declare the following to be a full, clear,and eXact description of the same, reference being had to .theaccompanying drawings, making a part hereof, in which- Figure 1,represents a top View or plan of the press. Fig. 2 represents Aa Viewfrom one ofthe sides. Fig. 3, represents a view.

of the side opposite to Fig. 2, and Fig. V4f', represents a verticallongitudinal section through the'press; Fig. 5, a View of a detachedportion.

Similar letters in the Several figures denote like parts.

The natureof my invention consists, more particularly, in the generalarrangement of the various parts of a printing press,lso as to combinegreat utility, with the simplest and cheapest manner of construction. t

To enable others skilled in the art to make and use my invention, \Iwill proceed "to describe the same with reference to the drawin s.

glhe frame A may be suitably and sub- Stantiallybuilt of cast iron, andin proper ybearings therein is placed the shaft B, carrying the balancewheel C, through which motion may be given .to the several parts of thepress by hand or any other power. At or about the center of the pressonthe shaft B, is secured a spur wheel D, whichr meshes vinto androtates a large gear 'Wheellv E, on; a`

shaft F., also supported in the frame A. Qn said shaft F, is also placedythe eccentric pins `(one only being seen in the section Fig. 4;)

forforcing up the platen, or for throwing off the impression, and whichwill be, hereafter, more fully described. The shaft F, carries on itsextreme ends, outside of the frame of the press, the two cam wheels G,(Fig. 2), and H, 3), in the face of which cam wheels are cut the ca mgrooves (respectively) a, b, yinto which kpins c, c5 on the arms I, J,work andgive'tov the rock Shaft K, the motions necessary kto .operate P.RUGGLES,

the springholders lo, as seen in the "and around the pulley T, which areforced up against the sheet by the rod Z.V

The spring holders/h, are hung on a rod f,

and in `said rod longitudinally is cut a slot (represented by a red linein Fig. 1,) into which av small projection on the boss or sleeve of thespring ts, and admits of said springs being run out or in on said rod f,so as'tobe adjusted to the size or shape of the paper to be printedupon. `Around 'the rod f, is coiled a small spring m, which winds up asthe platen plate N, goes downthe spring holders la, being forced upagainst thepaper by the fixed rod .or bar n, against which they rest.`When the platen comes up, the uncoiling of thef spring Wo, throws outdrawing, and releases the sheet. i The ink trough P, is hung upon theframe `by springs o, 0, which allows it, and ink f 'roller Q, hung init, to adjust and adapt themselves to the intermediate ink roller Rwhich, isplaced betweenthe ink rollers O,

Q, for conveying theuink from one to the otherI of, said rollers. On theend of the roller Q, is a ratch p, into which a weighted `pawl may workso as to'rotate the roller in theinktr'ough, and said roller may also begrooved with shallow small grooves, for

.betterV carrying up and distributingthe ink.

The roller O, may have a double thread or screw cut upon one of AVitsends .for giving it a' transverse motion, in addition to itsrotaryinotion, which last it receives from the pulley S, ,on the shaft Byby means `of a twisted or crossed belt g, passingaround it, is attachedto the axis of said roller O. Y

Thefpaper table AU,is so placed,.that the sheets,` or other thing to beprinted upon may be conveniently placed `on the platen plate'N, where itis caught bythe spring holders, as before described and carried down -towhere it is to receive the impression-the form having been previouslyinked by the rollers `e, e. `The eccentric pin r on the shaft F,thencatches into'the toggle arm V, and' forces up the platen against theform. Thebed W is permanentlyXedv to the frame by the screws s, s, andshould be Asufhciently rigid to receive the pressure of .the platen. Theguide piece L, hasarms t t,4at each end of it which unite inaspringplate (shown by dotted lines in` F ig: 4) said Vplate having slots in itthrough which set `pushing down said handle, the impression.

screws pass, by which the inking rollers may 'be allowed to yield oradjust themselves to thejplaten plate.

The' platen X, is hung` upon the curved arms Y, (one only being seen inFig. 4)-

the other ends of v.said arms Y, being atV i tached to a rock shaft Z,which issupported inthe frame of the press. In the `same rock shaft Z,is also, placed, the Vspring arms u (one 'only being seen) which supportthe inling roller R, and which roller, whe'nlthe platen is forced upagainstthe b ed or form, is thrown, by the partial rotatron' of saidshaft Z, against the roller l '1n the lnk trough for the purpose ofreceivlngfanother supply of ink. j

The impression is regulated by means lof four screws o, c, (two onlybeing seenin Fig. 4, in red lines) one at each corner of the platen, bywhich means a form may be workedin any part of the platen. The bed beingstationary, and the platen vibrating, but confined at the two corners,cannot yield out of itsplane, these set screwstherefore make upaperfectadjustment of theimpresi sion. j

The toggle arm V, has a cord fw, attached to it which passes up andaround a pulley m, to which there is a handle 4conveniently placed nearwhere the paper is placedon the platen plate, so` that the operator, bymay throwf'oif Fig. 5, represents a perspective view `of the spring armor plate which` carries theguard i i vor guide plate h, detached fromthe press,

`and shown in placeinjdotted lines in Fig. 4,

inl which `l represents thejslots, and 2-the set screws therein to allowit to move-from the platen or platen plate,and 3 a coiled spring `behindit, (represented in dotted lines), one end of which spring'is fastenedto said plate-the other endto the frame of the press, the object of the"spring being to allow the rollers` to adjust themselves'to the theextent of their movement. When `the rollers have passed down, and theimpression is taking the guides z, (there being one at each side of thepress,) as well asthc form or the spaces between the forms, so as toallow the sheet to come fairlyupllto the form.

2. I also claim hanging the platen X, and the intermediate ink roller R,to the same rock shaft Z, by their respective arms Y,

and u, so that the vibration of the platen, shall throw the intermediateroller, first, to the grooved ink roller Q, and then to the ink bearerO, for the purpose of receiving 410 Q and distributing the ink from theink trough at every vibration of the platen subf Witnesses:
